Equine atypical myopathy, also known as atypical myoglobinuria, or EAM is a mortal disease of horses (equidae) characterized by acute rhabdomyolysis. It is believed to be caused by the ingestion of the seeds (or young shoots) of Acer pseudoplatanus in Europe and Acer negundo in America. EAM has a high mortality rate and numerous fatalities have occurred.
